Telecentric lens yog ib homoptical lens, tseem hu ua TV lens, lossis telephoto lens.Los ntawm kev tsim lub lens tshwj xeeb, nws qhov focal ntev yog qhov ntev, thiab lub cev ntev ntawm lub lens feem ntau me dua qhov ntev focal.Cov yam ntxwv yog tias nws tuaj yeem sawv cev rau cov khoom nyob deb uas loj dua li lawv qhov loj me, yog li nws tuaj yeem ntes qhov chaw nyob deb lossis cov khoom kom meej meej thiab nthuav dav.

Telecentric lo ntsiab muag tau siv dav hauv cov xwm txheej xws li kev ua kis las, kev yees duab tsiaj qus thiab xwm, thiab kev soj ntsuam hnub qub, vim tias cov xwm txheej no feem ntau xav tau kev tua lossis saib cov khoom ntawm qhov deb.Telecentric lo ntsiab muagtuaj yeem nqa cov khoom nyob deb "los ze zog dua" thaum tswj qhov tseeb thiab nthuav dav ntawm daim duab.

Tsis tas li ntawd, vim qhov ntev focal ntev ntawm telecentric lo ntsiab muag, lawv tuaj yeem ua tiav tom qab qhov muag plooj thiab qhov tob tob ntawm qhov chaw, ua rau cov ntsiab lus tseem ceeb dua thaum tua, yog li lawv kuj tau siv dav hauv kev yees duab portrait.

Lub telecentric lens

1.Cov yam ntxwv tseem ceeb ntawm telecentric lo ntsiab muag

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub lens telecentric yog siv nws cov qauv tshwj xeeb kom tawg lub teeb sib npaug thiab tsim cov duab mus rau lub sensor lossis zaj duab xis.Qhov no tso cai rau nws ua tiav cov txiaj ntsig zoo dua thaum tua scenes nyob deb ntawm qhov kev kawm.Yog li, dab tsi yog cov yam ntxwv ntawm telecentric lo ntsiab muag?

High-precision duab:

Lub ntug imaging ntawm lubtelecentric lensyuav tsis khoov.Txawm tias nyob rau ntawm ntug ntawm lub lens, cov kab tseem tuav tib lub kaum sab xis sib tshuam nrog lub hauv paus axis ntawm lub lens, yog li cov duab siab tuaj yeem ua tau.

Muaj zog peb-dimensional kev nkag siab:

Vim hais tias ntawm orthogonal projection, lub lens telecentric tuaj yeem tswj cov kev sib raug zoo ntawm qhov chaw, ua rau cov duab ntes tau muaj kev nkag siab peb-dimensional.

Parallel kab:

Vim yog qhov tshwj xeeb sab hauv kho qhov muag, lub lens telecentric tuaj yeem ua kom lub teeb nkag mus rau hauv lub lens sib npaug ntawm txhua txoj haujlwm, uas txhais tau hais tias cov duab kab ntes los ntawm lub lens yuav nyob ncaj yam tsis muaj dabtsi yog khoov lossis deformation.

2.Cov kev siv tseem ceeb ntawm telecentric lo ntsiab muag

Telecentric lo ntsiab muag tau dav siv hauv cov hauv qab no:

Daim ntawv thov kev ua duab

Hauv cov teb xws li lub computer tsis pom kev uas yuav tsum tau ua cov duab, telecentric lo ntsiab muag tau siv dav vim tias lawv cov duab zoo nkauj, uas ua rau cov duab ua tau zoo dua.

Cov ntawv thov kev lag luam

Telecentric lo ntsiab muag feem ntau yog siv rau hauv qee qhov kev tshuaj ntsuam xyuas uas yuav tsum tau ua kom pom tseeb.

Daim ntawv thov kev yees duabs

Hauv qee qhov kev yees duab,telecentric lo ntsiab muagfeem ntau siv, xws li architectural photography, khoom photography, thiab lwm yam.

Daim ntawv thov kev yees duab dav hlau thiab telephoto photography

Hauv kev yees duab dav hlau thiab kev yees duab telephoto, telecentric lo ntsiab muag tuaj yeem ntes cov duab nrog lub zog peb-dimensionality thiab siab precision, thiab tau siv dav.
